Great idea. I will probably do a similar thing myself at some point, and it will probably look similar to yours.

The only thing I see that might be missing is advise for a scenario in which the odds of revival go down with time, creating pressure to revive you sooner rather than later. In that case your wishes may contradict with each other (since later revival could still increase the odds of living indefinitely). That seems far fetched but not entirely impossible.

Other than that, I'd say be more specific to avoid any possible misinterpretation. You never know how much bureaucracy will be involved in the process when it finally happens.
